Bursting bubbles in Herschel-Bulkley fluids: dynamics and jetting transitions
A. H. Ghaemi, Z. Yang, A. Huang +3
When a bubble rises to a free surface, its bursting dynamics in Newtonian fluids are governed by the interplay between viscous, capillary, and gravitational forces. In this work, w…
Stood-up drop to measure receding contact angles
Diego Díaz, Aman Bhargava, Franziska Walz +9
The wetting behavior of drops on natural and industrial surfaces is determined by the advancing and receding contact angles. They are commonly measured by the sessile drop techniqu…
Holes in Sheets: Double-Threshold Rupture of Draining Liquid Films
Ayush K. Dixit, Chunheng Zhao, Stéphane Zaleski +2
Classical rupture is attributed to molecular (van der Waals) forces acting at nanometric thicknesses. Nonetheless, micron-thick liquid sheets routinely perforate far above the scal…
Rheology of Two-Dimensional Dilute Emulsions
Thomas Appleford, Vatsal Sanjay, Maziyar Jalaal
The single droplet under shear is a foundational problem in fluid mechanics. In computational fluid dynamics, the two-dimensional (2D) formulation offers advantages in both computa…
Bouncing microdroplets on hydrophobic surfaces
Jamie Mclauchlan, Jim S. Walker, Vatsal Sanjay +4
Intuitively, slow droplets stick to a surface and faster droplets splash or bounce. However, recent work suggests that on non-wetting surfaces, whether microdroplets stick or bounc…
Implementation of integral surface tension formulations in a volume of fluid framework and their applications to Marangoni flows
Mandeep Saini, Vatsal Sanjay, Youssef Saade +2
Accurate numerical modeling of surface tension has been a challenging aspect of multiphase flow simulations. The integral formulation for modeling surface tension forces is known t…
To jump or not to jump: Adhesion and viscous dissipation dictate the detachment of coalescing wall-attached bubbles
Çayan Demirkır, Rui Yang, Aleksandr Bashkatov +3
Bubble coalescence can promote bubble departure at much smaller sizes compared to buoyancy. This can critically enhance the efficiency of gas-evolving electrochemical processes, su…
